Having problems with your Pentax *ist D Digital Camera ?

Program mode I have a question about the program mode. there are 4 choices according to the manual: 1. Normal, 2-High-peed priority, 3-Depth-of-field priority, 4-MTF priority. I know I am going to feel stupid, but what is MTF priority? I wasn't any good at acronyms in the service either.

Answers :

MTF = Modular Transfer Function. MTF tests is a chart describing the lens performance (sharpness, contrast etc.) throughout the aperture range. All lenses has a "sweet spot", where the best performance is given. But this can vary, not just from lens type to lens type - but also sample to sample (due to manufacturing tolerances). Each sample of modern Pentax lenses (FA, and to my knowledge also DA) are MTF tested - and the aperture which gives the best performance is coded in the MTF chip and read by cameras supporting MTF program. MTF program line simply tries to set this optimum aperture, or coming as close as the light conditions allow.
MTF stands for "Modulation Transfer Function" ... It's a somewhat arcane name for one type of testing methodology used in modern lens analysis. \015\012\015\012The *ist D's MTF priority program mode sets the "best" aperture to use for a given ISO setting and meter reading based upon lens information encoded in the latest FA series lenses. Earlier series lenses do not include MTF information in their communication with the camera so I suspect it defaults to Normal program mode when non-FA lenses are used.

Overexposure problem I am using a Canon Rebel and have it set for RAW, 100ISO, and am deliberately Underexposing by 1 stop, but I am still getting Overexposed images. The histogram is weighted to the left. I am using it on P (program), Av (Aperture priority) and Manual modes. I am new to digtal and may be overlooking something obvious - can anyone help point out my or the camera's error?

All of a sudden every picture I take with the 55-200 zoom lens is blurry and slightly out of focus. Pictures with the 18-55 lens are still sharp. I have been using that 55-200 lens for years for sports shots, and have never had any problem. I get the same blurriness shooting in both the auto sports setting and in shutter priority. It is a brand new issue. Could it be the AF servos starting to go in the lens, or am I doing something stupid?


Simplest answer is that you may have accidentally flipped the focus switch (A/M) on the lens to M. This turns off autofocus for that lens (which you might need to do if autofocus just can't resolve the image). Try turning it back to A.Ano ... Nikon D40x Digital Camera

I have a nikon d200. The last time I used it (only a few days ago) it was fine, everything normal. Then yesterday I pull out out of the case and everything seems to be going wrong. It is metering INSANELY low, like a shutter speed of 100 in full daylight produces a REALLY dark image. It won't auto focus at all, and i am unable to change the fstop in manual or aperture priority modes. I tried to restore it to factory settings and the lcd screen flashed to indicate it had been restored but no luck
